Title: Structure of flat cold cathode, drive method and electron beam emitting device using thereof
Inventor: KUSUNOKI TOSHIAKI
IPC: H01J1/312
Filed: 1994-12-21
Abstract: PURPOSE: To emit electrons stably with high efficiency with slight dependence on vacuum degree and with no need of use of alkali metals by applying an external electric field from an opposite electrode to the surface of an electron emissive part in which a large number of small dots with height within a range from several nm to 20nm. CONSTITUTION: A metal-insulator-metal structure composed of, for example, Al for a lower part electrode 12, Al2 O3 for an insulating layer 11, and Au for an upper part electrode 10 is employed for a cold cathode. Dots 14 with several nm to 20nm height are formed regularly since electric field evaporation of Au from a probe coated with Au and of an atomic force microscope and scanning by the probe are carried out reciprocally. A panel-like cold cathode is formed from a large number of fine cold cathodes having uniform dots 14 and a flat electrode 17 in which apertures 18 are formed at the positions on the opposite to the electron emitting parts of the fine cold cathodes is installed.  When high voltage is applied between the electrodes, electric fields are converged in the dots 14 and the practical work function of the surface of the cold cathode is lowered and hot electrons are emitted by Schottky effect.

IPC: G03G15/08
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a new wire module support structure for controlling the interval and edge angle of an electrode wire against a donor roll in a scavenge- less developing system. SOLUTION: A support node face 102 for a wire 42 is formed into an arc shape having a round edge support face, and it is fitted concentrically with a donor roll shaft 44 near the end section of a donor roll 40.

Title: Scanning optical system and laser beam printer using same
Inventor: YAMAMOTO YOSHIHARU
IPC: B41J2/44
Filed: 1988-12-16
Abstract: PURPOSE:To correct a shift in image plane position in a subscanning direction by varying the refracting power of a cylindrical lens which constitutes a 1st image formation optical system. CONSTITUTION:Parallel luminous flux from a semiconductor laser light source 1 passes the 1st image formation optical system composed of the variable refracting power cylindrical lens which has refracting power only in the subscanning direction. Then the luminous flux is deflected by the deflecting and reflecting surface 4 of a rotary polygon mirror 8 to form its image on a scanned surface 6 through a 2nd image formation optical system 5 and the light is also scanned as shown by an arrow 7. In the subscanning direction, on the other hand, the luminous flux is imaged nearby the reflecting surface 4 through the lens 2. Here, when the polygon mirror 8 rotates to perform deflecting operation, there is a deviation generated between the position of the reflecting surface 4 and the linear image formation position by the 1st image formation system. This deviation is varied by controlling the refracting power of the lens 2 in every period of the deflection to suppress variation in spot diameter due to the movement of the image plane position in the subscanning direction.

Title: Micrometer
Inventor: NISHIOKI NOBUHISA
IPC: G01B3/18
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a micrometer which can reduce measuring error due to deformation of a frame and is capable of cost reduction and weight reduction. SOLUTION: Deflection deformation is generated when a measuring pressure is applied to a frame 11 in the case of measurement. Since the frame 11 is formed almost in an S-shape, nearly equal deflection deformations in the outside direction are generated on both sides of the frame 11 on the boundary of a center point 11C, and an anvil holding part position and a spindle holding part position of the frame 11 are held in parallel. Attitudes of the anvil 12 and the spindle 15 which are held by the respective holding parts are also held in parallel with each other. Relative inclination between an anvil surface 12A and a spindle surface 15A does not exists. Thereby an object to be measured can be clamped always in the same attitude between the anvil 12 and the spindle 15, and measuring error due to deformation of the frame 11 can be reduced.
